Cancer is a disease in which some cells in the body grow out of control. There are many different types of cancer, and each begins when a single cell acquires a genomic change (or mutation) that allows it to divide and multiply uncontrollably. If there are additional mutations, the cancer can spread to other sites.]]> 2023-02-22 19:51:22 UTC https://padlet.com/majusalazar20/1kzh2cvw1i9vc0ky/wish/2491664415 HISTONE majusalazar20 https://padlet.com/majusalazar20/1kzh2cvw1i9vc0ky/wish/2491667897
Histones are critical proteins in the packaging of DNA in the cell in the form of chromatin and chromosomes. They are also very important for the regulation of genes. We used to think of histones as basically acting as suitcases that stored and held DNA, but it's very clear that histones are subject to regulation and have a lot to do with turning genes on and off.

The name comes from its structure. DNA has a central part with a sugar and a phosphate, to which molecules called bases are bound. Deoxyribose refers to sugar, and nucleic acid is the acid formed by phosphate and nitrogenous base. These bases can be of 4 types Adenina, citosina, timina y guanina, usually referred to as A, C, T, G. And the order in which they combine one after the other, is what encodes the genetic information.

In essence, it refers to the chemical modification of a DNA sequence. Do not forget that in this case the DNA sequence itself does not change. These modifications of the DNA sequence occur in a cell – usually in a germ cell, either an egg or a sperm – and this change is passed from one generation to another.

Epigenetics is the study of changes in the function of genes that are hereditary and cannot be attributed to alterations in the DNA sequence. The term epi means above. It is a Greek prefix. It is also defined as above the base sequence of DNA. In general terms it can be compared with the accents of words where the DNA is the language and the modifications are the accents.]]> 2023-02-22 20:13:09 UTC https://padlet.com/majusalazar20/1kzh2cvw1i9vc0ky/wish/2491687727
